Reception

Reviews of the Nikon D40 have been generally favorable due to its ergonomics and image quality. It received some criticism for some design compromises Nikon undertook to keep the D40's price and size competitive.

Nikon D40x

On March 6, 2007, Nikon introduced the D40X, a sister camera to the D40. While identical in external design to the D40, it has a 10.2-megapixel CCD sensor, continuous shooting up to 3 frames per second, and a base sensitivity of ISO 100. It has a flash sync speed of 1/200 of a second. A new consumer-level telephoto zoom with vibration reduction debuted alongside the launch. Nikon ceased production of the D40X in December 2007, shortly before they introduced its successor, the Nikon D60.
